How did the lettuce get the food molecules that we then eat?
Lettuce grows in the ground and we eat its leaves.
Your model should explain how lettuce gets its food molecules. Using words add the components and interactions you need to explain what is going on in the model below.
Make sure to include things we can't see with our own eyes but we know are there.
Add in other zoom-ins if you need them.
If needed, add a key to explain your representations.
